In the Church no one is a stranger, and the Church is not foreign to anyone, anywhere. As a sacrament of unity and thus a sign and a binding force for the whole human race, the Church is the place where illegal immigrants are also recognized and accepted as brothers and sisters. It is the task of the various Dioceses actively to ensure that these people, who are obliged to live outside the safety net of civil society, may find a sense of brotherhood in the Christian community.
Solidarity means taking responsibility for those in trouble. For Christians, the migrant is not merely an individual to be respected in accordance with the norms established by law, but a person whose presence challenges them and whose needs become an obligation for their responsibility. "What have you done to your brother?" (cf. Gn 4:9). The answer should not be limited to what is imposed by law, but should be made in the manner of solidarity.
